Patent DE-3908137-A1 (DE)
Title: Pipe connection
Inventor: VAHLBRAUK KARL HEINZ
IPC: F16L47/06
Filed: 1989-03-13
Abstract: In the case of a formation of a pipe connection of thick-walled plastic pipes by means of a double socket, there is often the problem that, in the connection region, irregularities occur in the course of the inner wall which give rise to considerable turbulence and thus to cavitation. Furthermore, the irregularities in the course of the wall often form the starting point for encrustation, with the result that problems in terms of hygiene also arise. A pipe connection according to the invention by means of a double socket (3) is characterised in that there is integrally formed, on the basic body (4) of the double socket (3), an annular body (5) which is inclined inwards in the flow direction (6), acts at the same time as a sealing body and on whose two side surfaces the mutually complementary pipe ends (1, 2) bear in a sealing manner. Radially on the inside, the annular body is designed such that a pipe-wall progression which is smooth on the inner-wall side is obtained. <IMAGE>
Patent DE-3911082-A1 (DE)
Title: Process and apparatus for reprocessing articles of plastic and/or rubber with metallic inserts, in particular scrap tyres
Inventor: FALLER SEN ALEXANDER
IPC: B29C35/08
Filed: 1989-04-05
Abstract: The problem in recycling scrap tyres with metallic inserts is that the separating tools used for this are subjected to considerable wear and satisfactory separation of the metallic inserts from the rubber of the tyre is not possible. Similar difficulties arise in the case of other articles of rubber and/or plastic with steel inserts. In the invention this problem is solved by the article (18) being electrothermally treated, so that the metallic inserts (24) are intensely heated and thereby break down into small particles or lose their hardness and strength by annealing; at the boundary layers, the rubber heated here breaks down into carbon dust. In this way, subsequent shredding and simple separation of the metal parts from the rubber parts is possible. <IMAGE>

Patent DE-3942977-A1 (DE)
Inventor: SCHRODI KARL DIPL ING
IPC: H04L12/56
Filed: 1989-12-23
Abstract: State of the art (not public): In order to load an ATM switching network as evenly as possible (even in the short term) and thereby minimise cost, the consecutive cells of one and the same connection are switched through to the exit via as many different paths as possible. 
<??>Technical problem: Reciprocal overtaking of consecutive cells must be avoided or corrected. 
<??>Fundamental principle: Each cell is held at the output until it is ensured that no preceding cell can still be temporarily stored in the switching network. Before the cell is forwarded, a check is carried out to ascertain whether, among the cells leaving the switching network at a later stage, a preceding cell is still present which is to be forwarded before it. 
<??>Implementation: Sequence numbers are assigned to the cells on the input side (either on an individual connection basis or not). On the output side, a buffer memory (1) is provided which is operated at least partially (1, ..., d) in the manner of a shift register and thereby produces a predefined delay. Before the output of a cell, at least the part of the buffer memory which is operated in the manner of a shift register is interrogated to ascertain whether a cell registered at a later stage is to be output earlier. If it is, the two cells are exchanged.

Title: FET-controlled transformer-based DC=DC push=pull converter - features centre-tapped matching transformer with FET-switched prim. and sec. windings
Inventor: WOELFEL WERNER ING GRAD
IPC: H02M3/335
Filed: 1991-02-06
Abstract: The arrangement for a push pull transducer comprises two capacitors (C1,C2), a series inductor (L) and a transformer (T) with matching centre tapped prim. and sec. windings. Four identical FETs are located on either side of the centre tappings of the transformer prim. (transistors T1 and T2) and (transistors T3 and T4) windings. The gate contacts of the FETs are controlled by timing signal voltages (VT1,VT2,VT3,and VT4) arranged so that VT1 = bar VT4 and VT2 = bar VT3. Gate timing signals VT1 and VT2 are synchronised so that the prim. circuit transistors never conduct simultaneously, whereas timing signals VT3 and VT4 are arranged so that the sec. circuit transistors conduct simultaneously for a short period, reducing the sec. circuit impedance and improving the overall transducer operating efficiency in comparison to single ended transducer circuits. ADVANTAGE - FET circuit uses less power and occupies smaller physical vol. than comparable bipolar transistor circuits.
